To allwhom may concern:

it Be'it known that I, ARTHUR GF. I'TATCH, a citizen of the United.States, residlng at Duluth, in the county of St. Louis and State ofMinnesota,have invented certain new and useful- Improvements in BuildingConstruc- .tion, of which the following is a specification. 1

This invention relates to a new and improved-budding constructlon, andmore par- 1 ticularly to a wall construction comprising a .plurality ofseparate wall elements In building construction the building wall shouldkeep out moisture and cold and retain the warmth of the building itself,and furthershould be adapted not, to transmit sound. cured by providinga wall having 1nsulating air spaces. this air space he so formed as toprevent ready passage of air currents. It is a wellknown: principle thatwhere air currents tendto passthrough a restricted area and thenthroughenlarged spaces, the air itself. builds up secondary air currentswhich retard its passage.-- .Due to this fact the airspaces mayberontinuous and yet be so 4 formed as to prevent free passage of theair with. its consequent heating or cooling effect." I

It is an object of the present invention to provide new and improvedwall structure which is composed of a plurality of walls each comprisinga multiplicity of block ele ments.

It is a further object to provide a structure of this character which iscapable of a variety of methods of assembly.

It is an additional object to provide a structure which is composed ofbut few forms of elements, the various elements be ing interchangeableand of shapes which may be readily constructed and handled.

Other and further objects will appear as the description proceeds.

I have illustrated certain preferred embodiments of m invention in theaccompanying drawings, in which- Figure 1 is a fragmentary section1llustrating my improved wall construction with associated floorconstructions;

has as -l5ieferring first to the form of wall shown in Figure 1, theouter wall at'the left of the figure comprises a plurality of blocks ofthe type shown in Figures 2, 3 andv4. These blocks each comprise a facewall 20, upper and lower flanges 21, and end flanges 22and a transverseseptum 2 8. As best shown in Figure 4, the upper and lower flanges 21are formed with straight inner surfaces slopv ing inwardly in suchmanner that the flanges increase in thickness toward their junction withthe wall 20. The end flanges 22 are formed upon an arc of a circle, thecenter of curvature being preferably located substantially at thejunction of the front and end faces. This particular curvature greatlyfacilitates the removal of the blocks from the mold. The blocks may beformed with a continuous groove 24: extending around the. face of theflanges. This groove is adapted to receive bonding mortar or to receivereinforcing rods. i

In the form of wall shown in Figure 1, two separate walls are built upwith blocks of the type shown in Figures 2 t0 4, the blocks beingoppositely faced to bring their flanges toward each other. In thedrawing the wall rests upon the foundation 25, a special block 26 beingplaced directly upon the foundations. This block is provided with aninwardly facing shoulder 27. The floor 28 rests both upon the foundation25 and the shoulder 27. The surface between the floor slab and the block26 is preferably coated with tar or with a sheet of tarred paper inorder to prevent transmission of moisture from the outer face of theWall to the floor, or vice versa.

The weep pipe 29 passes down through the floor and foundation from theintermediate cavity in the wall and is adapted to carry off any moisturewhich may form within the wall. The oppositely faced blocks 30 rest uponthe floor and the special blocks as shown. Subsequent floors are formedas was the floor 28, with the exception that the floor rests directlyuponthe inner wall and part ofitsload istllansmi ted to the outer wallby gthcspecial block 26. The flOOr is provided with aweep pipe 32 topermit passage of ,moisture. v -The 5, binding elements 38 used inthisform of wall are clearly shown in Figures 1 and 5. 'The'se bondingelements are blocksextending transversely betweenthe two iseparatedwalls and as shown in the figures, the blocks 10 f are placedinstaggered relation sothat theair space is not interrupted-at any .point.They are inserted by breaking away the (upper and lower. flanges of theblocks at the points at which the bond blockis placed,
